Struct RenderCacheKey 

pub struct RenderCacheKey {
    pub content_hash: u64,
    pub terminal_width: u16,
    pub tool_expanded: bool,
    pub tool_density: ToolDensity,
    pub show_labels: bool,
    pub theme_generation: u64,
}

Cache key for a single rendered chat message.

Two keys compare equal only when the content, terminal width, theme generation, and all display flags are identical. Any mismatch causes a cache miss and re-render. The theme_generation field increments on every theme swap, forcing a cache miss after the user switches themes so that cached Lines (which bake in theme Style values) are not reused with stale colours.

Examples

use zeph_tui::render_cache::RenderCacheKey;
use zeph_config::ToolDensity;

let k1 = RenderCacheKey { content_hash: 1, terminal_width: 80, tool_expanded: false, tool_density: ToolDensity::Inline, show_labels: false, theme_generation: 0 };
let k2 = RenderCacheKey { content_hash: 1, terminal_width: 80, tool_expanded: false, tool_density: ToolDensity::Inline, show_labels: false, theme_generation: 0 };
assert_eq!(k1, k2);

Fields

content_hash: u64

FNV/xxHash of the message content string.

terminal_width: u16

Terminal column width at the time of rendering.

tool_expanded: bool

Whether the tool-output section is expanded.

tool_density: ToolDensity

Current tool-output density level.

show_labels: bool

Whether source-label badges are shown on assistant messages.

theme_generation: u64

Monotonic counter bumped on each theme swap; forces cache miss after a switch.
